Welcome to Mr Mind

Mr Mind© is a virtual version of the classic game Master Mind.



The free demo version displays a tedious splash screen at startup. If you would like to obtain the full version of the game and thereby contributing with $5 to the programmer's coffee to be drunk during code-writing please send an email to The full version will be mailed directly to you.


Game rules

You play according to the standard rules defined for the original board game. The opponent (the computer) selects four blobs with random colors and keeps them hidden from the player (you). It is allowed for several blobs to have the same color. The player then selects a choice of four blobs and places them in corresponding positions in the board's bottom row. After pressing "OK" the computer responds by displaying up to four indicators which can be black or white. Black indicator means that a blob was placed at a correct position. White indicator shows that a blob was placed in an incorrect position but that the color is present in the computers hidden combination. Play until the computers combination is solved.
